If you’re like most people, you probably don’t know your way around a percentage calculator. Here are some quick tips on how to calculate 20 percent of 42.

## What is 20 percent of 42

When it comes to calculating percentages, the number 42 is an important one to know. After all, 20 percent of 42 is equal to 8.4.

But what exactly is a percentage? According to the Merriam-Webster Dictionary, a percentage is “a part of a whole expressed in hundredths.” So, when we say that 20 percent of something is equal to 8.4, we’re saying that 20 out of every 100 parts of that something is equal to 8.4.

Now, let’s take a look at how to calculate 20 percent of 42 using the percentage formula. The percentage formula is: Percentage = Part ÷ Whole × 100. So, plugging in our values for the percentage formula, we get: 20 percent = 8.4 ÷ 42 × 100.

Solving this equation, we find that 20 percent of 42 is equal to 8.4.

It’s important to note that the answer to this equation will always be a decimal. This is because percentages are always calculated out of 100 and decimals are just another way of expressing fractions with a denominator of 10 or 100.

So, there you have it! Now you know how to calculate 20 percent of 42.

## What is 40 percent of 21

It is often said that 40 percent of something is a lot. But just how much is 40 percent of 21?

To answer this question, we first need to understand what 40 percent actually means. In mathematics, percentages are a way of expressing a number as a fraction of 100. So, when we say that 40 percent of 21 is a lot, we are saying that 40 out of 100 parts of 21 is a lot.

Now, let’s take a look at what 40 percent of 21 actually is. To do this, we will need to use a little bit of basic arithmetic.

If we divide 21 by 100, we will get 0.21. This means that 21 is equal to 2.1 percent of 100. To find 40 percent of 21, we simply need to multiply 2.1 by 40. Doing this gives us 84.

So, in answer to the question, 40 percent of 21 is 84.

## What is 10 percent of 84

What is 10 percent of 84?

This is a simple math question that can be easily answered with a little bit of basic arithmetic. To find 10 percent of 84, simply multiply 84 by 0.1.

The answer is 8.4. So, 10 percent of 84 is equal to 8.4.

## What is 5 percent of 420

It is often said that mathematics is the language of the universe. And while that may be true, there is no denying that percentages are one of the most useful tools that we have at our disposal for understanding and communicating information about the world around us. So what is 5 percent of 420?

To answer this question, we first need to understand what a percentage is. A percentage is a way of expressing a number as a fraction of 100. So when we say that something is 5 percent of 420, we are saying that it is five one-hundredths of 420.

Now that we know what a percentage is, let’s see how we can use this information to answer our original question. To find out what 5 percent of 420 is, we can simply multiply 5 by 420 to get 2,100. So 5 percent of 420 is 2,100.

But what if we want to express this answer as a fraction or a decimal? We can do this by dividing 2,100 by 100 to get 21/10, or 2.1. So 5 percent of 420 is equal to 21/10, or 2.1.

Finally, let’s take a look at how we can use percentages to solve real-world problems. For example, let’s say you’re trying to figure out how much tip to leave at a restaurant. If the bill comes to $42 and you want to leave a 20 percent tip, you can use the following equation:

0.2 x 42 = 8.4

This equation tells us that 20 percent of 42 is equal to 8.4. So if you want to leave a 20 percent tip on a $42 bill, you would need to leave $8.40.

As you can see, percentages are a incredibly useful tool for understanding and communicating information about the world around us. The next time you’re faced with a problem that requires you to find a percentage, don’t hesitate to put your skills to the test!

## What is 2 percent of 4200

What is 2 percent of 4200?

This is a common question that many people have. The answer is quite simple, but it may not be what you expect.

2 percent of 4200 is actually 84. This may seem like a small number, but it’s actually quite a lot when you think about it.

To put it into perspective, 2 percent of 4200 is equivalent to 8.4 percent of 1000. This means that if you had $1000, then 2 percent of that would be $84.

Now, let’s look at another example. Say you wanted to save up for a new car and you had $4200 saved up. If you put 2 percent of that into savings, then you would have $84 saved up after one year.

It may not seem like much, but over time it can really add up!

## What is 1 percent of 42000

When it comes to percentages, 1% is one one-hundredth. So, when we’re dealing with a quantity like 42000, we can divide it by 100 to find out how many “one one-hundredths” are in it. This gives us 420. So 1% of 42000 is 420.

It’s easy enough to calculate 1% of most quantities, but what if we don’t have a calculator handy? We can still estimate pretty closely by using some simple mental math.

If we know that 1% is one one-hundredth, then 10% must be ten one-hundredths. And since 10% is just 1/10, we can say that 100% (or “the whole thing”) is ten times as much as 10%. In other words, 100% is the same as 10/10, or 1.

Now let’s go back to our original quantity, 42000. We can mentally break this down into two parts: 4 and 2000. 4 is just 2 less than 6, so we can say that 4 is approximately equal to 6/10. As for 2000, this is just 20 less than 3000, so we can say that 2000 is approximately equal to 30/100.

Putting these two estimates together, we can say that 42000 is approximately equal to (6/10)*(30/100), or 0.18. Therefore, 1% of 42000 is approximately equal to 0.18 * 100, or 18.

## What is 0.5 percent of 84000

If you’re like most people, you probably don’t know what 0.5 percent of 84000 is off the top of your head. In fact, you might not even know how to calculate it.

But don’t worry, we’ve got you covered. In this article, we’ll show you how to calculate 0.5 percent of 84000 using a simple method that anyone can do.

Here’s what you need to do:

1. Take 84000 and divide it by 100. This will give you 840.

2. Take 840 and multiply it by 0.5. This will give you 420.

3. The answer is 420. This means that 0.5 percent of 84000 is 420.

That’s all there is to it! Now you know how to calculate 0.5 percent of 84000.

## What is 0.2 percent of 420000

In mathematical terms, what is 0.2 percent of 420000? This question can be rephrased as “What is 0.002 times 420000?” The answer to this question is 840. In other words, 0.2 percent of 420000 is the same as 840.

To put it another way, if you were to take 420000 things and divide them into 1000 even groups, each group would contain 420 things and 0.2 percent of 420000 would be equivalent to two groups. This is also the same as saying that 0.2 percent of 420000 is the same as 8400 divided by 10.

It’s worth noting that 0.2 percent is the same as 2 per 1000 or 2 ‰. Therefore, 0.2 percent of 420000 can also be written as (420000 * 2) / 1000 which equals 840.

## What is 0.1 percent of 4200000

0.1 percent of 4200000 is 4200.

## What are some other ways to calculate 20 percent of 42

If you’re not a math whiz, don’t worry – there are plenty of other ways to calculate 20 percent of 42. Here are a few methods that might come in handy:

1. Use a calculator. This is probably the easiest way to calculate 20 percent of 42. Simply enter 42 into your calculator, then hit the multiply button, followed by the equals button. The result should be 8.4.

2. Convert to decimals. Another easy way to calculate 20 percent of 42 is to simply convert both numbers to decimals. To do this, simply move the decimal point two places to the left for both numbers. So, 42 becomes 0.42 and 20 becomes 0.20. Then, multiply these two numbers together to get 0.084 – which is the same as 8.4.

3. Use a percentage conversion chart. If you happen to have a percentage conversion chart handy, you can use it to quickly and easily calculate 20 percent of 42. For example, on a standard chart, you would find that 1 percent is equal to 0.01, 2 percent is equal to 0.02, and so on. So, 20 percent would be equal to 0.20. To calculate 42 percent, simply multiply 0.20 by 42 – which gives you 8.4.

4. Estimate using mental math. This method isn’t recommended if you’re looking for an accurate answer, but it can be helpful if you need a quick estimate. To do this, first round both numbers up or down to the nearest 10 – so 42 becomes 40 and 20 becomes 20. Then, calculate 20 percent of 40 – which is 8. Finally, add 2 to this answer to account for the extra 2 in the original number (42). This gives you a final answer of 10 – which is close to the actual answer of 8.4.

5. Use proportions. This method is similar to the mental math method, but it’s a little more accurate. To set up the proportion, you need to know that 100 percent is equal to 1 (or 100/100). So, if 100 percent is equal to 1, then 50 percent must be equal to 0.50 (or 50/100), and 25 percent must be equal to 0.25 (or 25/100). With this in mind, you can set up the following proportion:

0.20/0.25 = x/42

To solve for x, simply cross-multiply – meaning you’ll multiply 0.25 and 42 together, and multiply 0 .20 and 25 together:

0 .20 * 42 = 8 .40

0 .25 * 25 = 6 .25

——————

8 .40 = 6 .25

——————

x = 6 .4

So, 20 percent of 42 is approximately 6 .4 – which is close to the actual answer of 8 .4
